“The Letter of Authority (LOA) is a key piece of paperwork when it comes to switching your energy tariff”

A Letter of Authority allows a Third Party Intermediary (TPI) to purchase energy and liaise with your current supplier on your behalf. Letter of Authority (LOA’s) are used in a multitude of industries as well as the energy sector, including financial and medical – the Letter of Authority is a recognised legal document.

Our raison d’être is to get your business cheaper gas & electricity rates; but, before we can do that we need your permission.

Letter of Authority – What we can do…

Manage any administrative tasks (the time-consuming stuff you hate doing!) on your behalf, such as:

  • Provide notice of termination to your existing supplier (with your consent)
  • Confirm your existing contract information
  • Raise and deal with complaints on your behalf if you are unsatisfied with a supplier’s service
Letter of Authority – What we can’t do…

We can’t agree to a contract without your permission, so you’re not signing your life away!

All you’re doing is giving us permission to speak to suppliers on your behalf. This process is standard across the whole industry.


Once we have your Letter of Authority, we can do what we do best… make sure your switch goes through without a hitch so all you have to do is sit back, relax and enjoy the savings!
